CARBURETER.

Specication of Letters Patent.

Application filed May 29, 191,4. Serial No. 841,820.

To all 'whom it may concern.'

Be it known that I, WILLIAM J. OMER, a citizen of the United States, anda resident of Thomas, in the county of Custer and State of Oklahoma,have invented a new and useful Improvement in Carbureters,.of which thefollowing is a specification.

My invention isan improvement in carbureters, and has for its object. toprovide a device of the character specified, adapted for use withinternal combustion engines of every character, wherein mechanism is-provided for thoroughly volatilizing gasolene or other liquid fuel, andfor mixing the volatilized fuel with air to provide for perfeetcombustion of the fuel.

The -primary object of the invention is to provide mechanism forcontrolling the mixture without the use of the'usual float valves, andwithout the necessity for adjusting the relative proportions of fuel andair in accordance with conditions of load and road.

A further object is to provide mechanism in connection with thecarbureter forheating the-mixture, before it passes to the combustionchamber of the engine.

In 'the drawingtsz-Figure 1` is an enlarged section taken on the line1-1 of Fig. 3, Fig. 2 is a section on the line 2 -2 of Fig. 1, Fig. 3 isa top plan view with parts broken away, and Fig. 4 is a partial sideview of a modified construction.

The present embodiment of the invention is shown in connection with thefuel tank 1, of an internal combustion engine,'the tank being of anyusual or desired form, and

receptacle as shown. A tubular casing or pipe 2 is arranged at thecenter of the tank,

extending through'the top or cover thereof to a point'near the bottom ofthe tank. At its upper end the pipe 2 is integrally connected to thecover by means of a ring 3, which extends above and below the top. Abovethe top the ring is reduced annularly to form a shoulder 4 near thevupper end thereof and above the shoulder the ring is screw threaded toreceive a cover. The cover comprises a concave-convex top 5 arrangedwith its convex surface upward, and an internally threaded ring 6 whichengages the threel` led portion at the top of the pipe 2, and the top5-is connected to thevring by arms 7, the said arms being arranged atangular intervals of 90 with respect to each other. The cover is squareas shown in Fig. 8, and the arms 7 are at the corners. The arrangementof the arms 7 provides for four openings for placing the interior of thecover in communication with the atmosphere. The .openings arenormally'closed by means of gates or valves 8, of frustopyramidicalform, each valve or gate being hinged to the cover as indicated at 9, atthe outer edge of the gate orvalve. The pipe 2 lis provided with anumber of annular series of openings 11 near its upper end, andcommencing just below the ring. tubular structure is arranged within thetank at the top thereof, the said structure l consisting of a seriesofstraight sections 12, and elbows 13 and 14 lfor connecting the ends ofthe straight sections with. each other. The elbows 13 and 14. are merelytubular, but the sections 12 may be described as split tubes and theyare arranged with the split on the under side thereof. Each of the saidsections is provided at each side of the split with a depending llangc15, and the flanges 15 of each section are'arranged in spaced andparallel relation. A sheet of wicking is supported by each of thesections 1'2 of the tubular structure, the said sheet being doubled uponitself to form folds 16 and 16a. The yjunction between the folds of eachsheet is held within the adjacent section 12, and mechanism is arrangedwithin the fold for holding the said fold or junction inclose contactwith the interior of the section. Thisv mechanism in the presentinstance, is a tubular casing 17 of gauze or the like,

the wicking .when the wicking is in contact with the interior of thesection. The folds 16 and 16a depend through the' split ofthe section,and between the flanges 15 of the section to a point at or near thebottom of the tank.

The sections12 are held in position near the top of the tank and abovethe `level of the liquid therein by means of transverse partitions 19',and each of the said partitions 19 is provided with an opening 20 atits'bottom for placing the entire tank in communication. The lower edgesof the flanges 15 are bent outwardly as shown at 21,4 and the said loweredges rest upon the upper edges of the partitions 19.

Detecting plates 22, 23 and 24 are arranged between the flanges 15 ofthe adja- Patented J uly 28, 1914.

of such cross section thatl it will fit within cent section 12, theseitig/plates differing only in width. The plats"22 are arranged betweenthe side wallpfbhe tank and the adjacent lange of the-.tadjacent section12. 5 The plate 24 isv arranged at the center of the tank between thetwo central sections, and the plates 23 are arranged between the lateralsection at each side of the tube 2. Each of the plate's'22,` 23 and 24is bent at its cen? rivets 27, arranged below lthe rivets 26.'

\ Each of the plates 22, 23 and 24 is provided with a longitudinalseries of openings 28 at l its center, and the .plate 24 has an openingthrough which the pipe 2cpasses. The folds of wicking extend only to theends ofthe .l sections 12, 'but the plates 22, 23 and 24 extend from oneend of the casing to the other,

' and are continued along' the ends of the casingas indicated at 29. Theplates 22-23- 30 24 and 29 are in fact an integral structure whichdivide the tank into upper and lower compartments, the`v liquid fuelbeing below the said partition, and the openings 28 provide acommunication between the compartments. lIt will be noted from aninspection of Figs. 1 and 3 that the outermost section 12 is extended atone end through the adjacent end ofthe tank, as indicated at 30, andthat the outermost section at the opposite end of the tank extends onlyabout half the length of the tank. An elbow 31 connects the free end ofthe section with a vertical pipe 32, which passes downwardly from theelbow through the bottom of the tank, being .reinforced-at the bottom'with a ring 33. An elbow 34 is connected with the lowerl end of thepipe 32 below the ring, and a section 35 of pipe is connected with theother end of the elbow. The pipe 35 is adapted for connection with themanifold of the engine, either directly or indirectly as conditio-nsmayy require. The usual throttle valve 36 is ar ranged in the section 35 ofpipe, thevalve being secured to the shaft or rod37, journaled-transversely of the pipe and provided at its outer end with the arm 38for manipulatingl the shaft. Screens 39- and 40 are arranged within thepipe 25 at spaced intervals, for

60 preventingdamage from backfiring. Should the flame from back ringpass the throttle valve, it would be checked by the screen.

A valve 41 is arranged within the extension 30, the said valvecooperating with the seat 42, and the valve is provided with fa ,monacistern 43, passingvthrough a spider 44 inthe pipe for guiding the stem. Acoil spring 45 encircles the stem between the spider and a stop 46threaded on to the rod, the spring acting normally to hold the valveclosed. The stop in the present instance is a nut and washer, and it'will be evident that the tension of the .spring may be varied by movingthe nut. One end of the spring is connected to the spider and the otherto the stop. In case of back firing the valve Vwill relieve any excessoressure'in the tubular structure, and

the valve may also be used for admitting air when necessary. The spring.45 may be arranged to hold the/valve partially open 1n order to admitair when conditions require more air than enters by way of the valves 8and thev openings/,11 of the pipe 2.

The device is also arranged in such manner that itmay be utilized'as aself starter for the engine. For this purpose a nip le or tube 47 isarranged transversely of t e top and extending through the same, and theouter end of the-tube is adapted for connection with a flexible pipe 48,the other end of which is connected with a suitable compressing device,as for instance, any means for compressing air, such as a bulb or pump.When it is desired to start the engine in this manner air under pressureis forced through the tube 47, and this air under pressure will enterthe openings 18, and will pass through f the tubular structure and thepipes 32 and 35 tothe engine.

[Mechanism may also be arranged within the tank 1 for heating thetubular structure, consisting of the pipes 12 and the elbows 13 and 14.This mechanism is shown in. Fig. 4, wherein resistance wires 49 and 50are arranged on opposite sides of the Vopenings -18a in the sections 12aof the tubularI structure. These sections have the depending 'flanges15, corresponding to the flanges 15, and the folds 51 ofwickingareconnected therewith and'with the sections in the same manner as abovedescribed. The resistance wires 49 and 50 are connected with a suitablesource of electrical energy capable of heating the wires. It will beobvious that when so con,- nected the pipeswill be heated and themixture passing through the pipes will be heated during its passagethrough the pipes. It

will be understood that any form of heater may be used in -thisconnection.

`The operation of the improved carbureter is as follows:-The fuel tankis filled with liquid fuel to about-the level shown, and in a very shorttime the depending folds 16 and 16 Vwill become saturated with thefueland by capillary attraction the fuel will pass into the tubularcasing. The wickA 'acts in the same manner as the wick of an oil lampand it will be evident that so long'as there is 'any fuel in the tankitv will be drawn into vthe tube. Nfter the wicking s been thormentarioughly saturated in this manner, whenever'l the engine is started in theusual manner air will be drawn through the openings in the cover 5,lifting the valves 8 and passing into the tube 2 and entering the body0f the tank through the openings 11. From the interior of the tank theair will be drawn into the tubular structure through the openings 18,andv will vaporize the fuel held by the wicking. As the air passesthrough the openings 18 and through the wicking to the interior of thetubular structure it will vaporize the fuel held` by the wicking andwill carry the same through the tubular structure to the engine.Wlienthe heating device' is used in connection with the tubing the airwill be heated as it passes to the engine. In

case a mixture of less richness were required the valve 41 would be opento admit a greater quantity ofair. lVhen it is desired to fill the tankor to renew the fuel the `cover is turned off from the upper end of thepipe 2, and the fuel is poured through the pipe 2 into the tank. Theplates 22- 23-24 are baffle plates to prevent the fuel splashing intothe upper part of the tank, and toprevent any non-volatilized fuelpassing through the engine. Any fuel that would pass above the -plateswill be returned to the body of the tank through the openings Q8.
